Gas Safety Certificate Lambeth — from £64.99

What is a Gas Safety Certificate (CP12)?

A Gas Safety Certificate, formally known as a CP12, is a document confirming that all gas appliances, flues and pipework in a rental property have been inspected by a Gas Safe Registered engineer and found to be safe. The engineer checks each appliance for correct operation, adequate ventilation, secure flue connections and correct gas pressure, and lists every appliance on the certificate along with its result.

Every private landlord in England has been legally required to hold a valid CP12 and renew it every 12 months since the Gas Safety (Installation and Use) Regulations 1998 came into force. This national duty applies in Lambeth as it does across England, and an HMO licence can add its own conditions on top.

Gas safety in Lambeth — local property context

Lambeth is largely a borough of flats: at the 2021 Census, 51.6% of households lived in purpose-built flats, against 40.3% across London. Houses are a minority, with 15.0% of households in terraced houses (London 21.3%), 7.8% in semi-detached and 2.0% in detached homes. A further 1.1% lived in commercial buildings such as flats over shops.

More Lambeth households rent from the council or a housing association than from a private landlord, and most private lets in the borough now need a council licence. Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the SW2, SW9, SW16, SW4, SW8, SE27, SE11, SE24, SE1, SE5, SW12, SE21, SE19 postcode areas, and regularly carry out CP12 inspections across Lambeth for private landlords, letting agents and HMO operators.

Gas safety in Lambeth: how the two application lists word it

When Lambeth made its case for borough-wide HMO licensing in 2021, gas leaks were among the cases its private sector enforcement team said it had dealt with.

The council's two application lists treat the gas document differently. The HMO list asks for the latest gas safety certificate if the property has gas, while the selective list names a gas safety certificate with no such qualifier. For an all-electric flat in a selective ward, ask the licensing team what it will accept in place of one before you submit.
